i have already seen that motor on many different sites but not in the original site of Sirio Engines... Whats going on with this motor? Its original or jut a tune of XXX by others who named it SIRIO XXX NEMESIS....??

this crankcase is like the xxxv,not the xxx.and i think that since the new orion abi is based in the xxx and not the xxxv noone else could take the xxxv platform.

Hi

I've seen that the bore and stroke measurement of the xxx Nemesis Engine are the same, 13.9 x 13.9!
Can someone tell me what this mean reguarding the power band of this engine?
Has this engine more bottom end or top end power?
Ohter engines like Nova, RB, Max have the long stroke version 13.8 x 14.2 and Picco, REDS,... the short stroke like 13.7 x 14.0.

It will have more HP than torque since it has a 'square' bore/stroke, but where it will all be focused really depends on crank timing and how the ports are designed.

switched to this motor a few races back,i was already leading our Local points .....but,when i started running these motors.....they all started scratching there heads....LOL!

Easy to keep in tune,ton of horse power.......a little grunt
on the bottom end...Good Miliage.. 5:45 per tank,on 20%...better with 16%..with the proper gearing (per track)...we run 3 different lots........just as fast as the rest!......

IMO.....
I am biased though!!

I Love My SIRIO'S

Where can I find XXX Nemesis and parts?
Even sirio official web site still stop update in 2010.

not sure but try......teamtrinity.com.....thats were my mills come from.......not sure about parts though.....i haven't needed any yet......

GoodLuck.
